To `lll w/'wmvz' hwy concern.'

Be it known that I; l/VILLIAM H. BURR, a

citizen of the United States, residingv at Chattanooga, in the county of Hamilton and i Combustion Engines, of which the following Pisa specification, reference being Ahad therein 4to the accompanying drawing.

y This invention relates to internal combus- State of Tennessee, have invented certain new and useful Improvements in Internaltio engines.

The invention is directed to means for in-y tro ducing a liquid, in the formY of steam or lother vapor, into the gaseous mixture flowing into the'f internal combustion engine, -whereby carbonizing of the interior of engine cylinder may be eliminated. y

One of its objects is to provide, in conjunction with such means, an instrumentality controlled bythe condition of the engine,

` wherebythe amount of vapor so introduced may be automatically regulated in accoudance with certain' predetermined requirements of the engine to which it is attached.

Another .object of the invention is the provision ofl means whereby the v'apor which is tobe introduced to the engine'V cylinder may be superheated before .its introduction,

' Other objects and advantages will. in part beI apparent and in part brought out inthe description which follows:

Drawings illustrating a'preferred embodiment of the invention are hereto appended, in which:h 4

ing 9, there is a p ipe llland in this pipe there is a valve 1 Suitablysecured -toy the kcasting of the vaporizer there is v afstemj1 3', adaptedpto be threaded'into the exhaustv manifold. .This stem is hallowed out on its exterior and is preferably placed in- -alinement with `the liquid receiving ropening of the casing, the

object being toreceive heat from the products of combustion whichpass through the exhaust manifold and communicate this heat to the interior of the hollow portion of the tube to vaporize, the incoming liquid.

Means are .provided for automatically regulating the amount of vapor to be introduced tothe engine cylinder, by effecting the regulation ofthe amount yof'liquid introduced to they engine. To this end, a thermostat 14 isfinclosedin the tubing and has its; lower "portion rest-ing on the bottom] f thereof. Its .upper portion is in engagement `with a. link 15 secured at one end to a standjard 16 disposed within the casing, the other end of the` link being in connection las 'through a rod 17'with a valve 18 disposed in the liquidl inlet opening. Normally the liquid 'enters the casing very slowly and is. almost immediatel vaporized.. The?. thermostat being'in t e direct passage of the liquid whi-ch'enters thecasing, itlwill be seen tha-t if toomuch vliquid enters the casing the rod will-"be cooled thus contracting. This contraction of the rod willbe communicated' through the links just described to the valve toclose the liquid inlet. I

The heating o'f the thermostatv Will hav the opposite effect-,namely to expand therod 'which in turn will open the liquid inlet I valvel permitting lmore liquid to enter the Fig. 3 1s a vertical sectional view of the' casing and become vaporized.

For the purpose o f superheatingrthe v vapors thus generated a-v pipe of the like v19 vapor from .the casing dueto the vacuum.

vcrea'ted'in the engine cylinder, there is provided a valve 21, in the air vent in the casing.

` From the, foregoing, it will be apparent' that my invention provides simple and eecytive'means-for producing-the results above i i ined-ien stated as desirable, and while ll have disclosed it in the embodiment herein shown it will be understood that many changes in the `construction and general arrangement will 5 be within thescope or lll/'hat l claim is: l. device iior .the invention.
